What class of drugs is used to dissolve blood clots?

Thrombolytics
Vasopressors
Antianginals
Antihypertensives

The correct answer is: Thrombolytics

Thrombolytics are a class of medications specifically designed to dissolve blood clots, a process known as thrombolysis. These drugs work by breaking down fibrin, a protein that forms the structural framework of blood clots. Conditions such as myocardial infarction (heart attack) or ischemic stroke, where there is a blockage in a blood vessel due to a clot, often require the use of thrombolytics to restore blood flow and minimize damage to the affected tissue. The other options refer to different classes of medications: vasopressors are used to increase blood pressure in critical care situations, antianginals help relieve angina (chest pain) by improving blood flow to the heart, and antihypertensives lower blood pressure to treat hypertension. While important in their respective contexts, none of these classes directly focus on dissolving blood clots.
